Correct Answer � D Explanation |

Ans. d. Lysosome
- The marking areas are centrally placed nuclei.
- The single nucleus of the cardiac muscle cell is located in the center of the cell.
- Myofibrils pass around the nucleus, producing a biconical juxtanuclear region in which the other organelles are concentrated.
- This perinuclear region is rich in mitochondria and contains a Golgi apparatus, glycogen granules, and lipofuscin granules.
